For anyone wanting to get PBT doubleshot backlit key caps, the iKBC staff have kindly pointed out to me that they will sell key cap sets of other color variants for this keyboard on https://mechanicalkeyboards.com . Let's hope it is coming soon. If you can't wait, iKBC G104 PBT doubleshot backlit replacement key caps are currently sold on http://www.taobao.com (if you understand Chinese). But the layouts are different from this one in terms of front side printed symbols, and it is 104 keys only (you have to do some mix and match).
